' illustrated in Figs. 2to 5, angle plates or facing plates 32 and33 ofextruded metal preferably of ornamental design are rigidly atare setrigidly in place relative tothe frame members 32 and 33. The frame 34 isbisected at the angle 35' by'a ertical metal bar 3601? substantially thecross sectional pattern shown in Fig. 2..v

An'-jannular metal sash section of; sub

stantiallyzthe cross sectional pattern shown in Fig. 2 and bisected atthe angle 35 by a vertical inetalbar 38 of substantially the crosssectional pattern shown in-Fig. :2, is constructed from 'miteredsections cut froin'bars of extruded metal carried .in stock for thepurpose. The sash section 37 is detachably and removably mountedrelativeto th rig idly mounted sash. section 34 toffa cilitate the insertion,removal, and adjustment of the glass panels 15 and 16into place In adjusting the detachablejs'ash section 37 f relative to the glass 'panelandthestationary or main sash'se'ction 34, since theglass panelis'usually'plate glass and, hence has its opposite faces ground toparallel planes, it

is desirable to adjust the edge 40 of sash section 37 into a planeparalleljwith the face of the glass panel or into planes parallel withthe respective glass panels in order to exert a substantially. uniformlydistributed contact -;pressure along the face 40'betweenfthe sashsection 37 and the face of'the glass panel. In orderto permit and insuresuch adjust ment of the sash section 37 relative to the section 34 andthe glass panel, a rib41 is formed preferably integral with the section34 .and a series of screws; 42 are threaded into perforations throughsaid rib 41 at spaced inteiy vals. The screws 42 are adjustable endwiserelative to the rib 41 to form a series of adjustable supports for. theedge 43 of thesash section 3'7, thereby enablingthe edge 43 to be spacednearer to;or further fromthe rib' 41, depending upon the thickness ofthe glass panel, until theedge 40 of section 3'? lies in a planeparallel to the face of the glasspanel and comes substantiallysimultaneously into contact with the face of the glass panel at allpoints along the edge 40, and so as to exert a substantially uniformpressure and strain between the edge 40 and the face of.

the glass panel. The opposite face of the glass panel engages the edge45 ofthe sash section 34 opposite to the edge 40 of the section 37. Aclose metal to glass joint is thus formed entirely encircling the glasspanel, and avoiding the use'of any rubber or other interposedsoft gasket,or packing material,

- which besides being expensive to provide andinstall, is unreliable toresist the severe wind, temperature and other strains to which thepanels and sashes are subjected. After the screws 42 have been adjustedto bring the face 40 flush with the face of the glass panel, a seriesof'spacedscrewsf46 are'employed to draw andclamp the two sash sectionstogether so=as to "hold the edge 43 in contact wit-h the heads of thespacing screws 42, and

so asf to clamp the glass panel between the edges40 and45; v 7

As illustrated the screws 46 are threaded into short; sections 54 cutfrom bars ofex- :truded metal of special-cross sectional pattern, andwhich areinterlocked and guided endwise of the sectionsi34- mea s ofsuitable'ribs or guides, asforinstance the ribs 41' and 51.

The s'crews'46 are tapped into the blocks54 andserveto clamp the sections 34 and 3'? together from the exterior of thesash. where it isfdesird to clamp the sections :34 and 37 together fromthe inside Iof'thelsash a series ofblocks 55-1cutfro1n bars of extrudedmetal "may bej'employed in place of the blocks .54, a'n'd'screws 56,'adjustable fromTtheQ inside and tapped into the blocks -55lmay beemployed in place of the screws 46.1 ;The'blocks-54 arewprovided withdovejtailedi channels ,intofwhich vare" fitted short sections ofleather, wood, soft rubber or siniilarmaterial 83'adapted to engage theedge'of the} glass panel, to support the weight of the panel. along thelower edge of the sash or to position the panelby'supporting its sideedges. r I a 1 Where two or more glass panels are mounted in one sash,eitheri'n' one plane as shown in mounting the panels19, 20 and 21,01where the glass panels are located in differ- ,ent planesas shown inmountingvthefpanels 15 and 17,. I preferably employ a metal cross rail36 stationarily attached at opposite ends to-opposite sides of thesash'section 34, and a metal cross rail"38stationa'rily attached atopposite ends to opposite sides of the saslr section37. Said cross'firails 36 and 38 are of extruded metal of special cross sectionalde-,.sign, jandare daptedtebe' cut from bars especially. provided forthepurpose and car ried in stock. Each of said rails 3 8 'isprovided withribs 52 projectinginwardly and forming between them a dovetailed channel5 7. Short blocks or sections 58, cut from are shaped to preventspreading the 5 2 waists and 17 are shown at an obtuse angle one to ethe other, and held in relative position by the cross bars 36 and 38. Asillustrated in Fig. 5,

a .the panels 19and 20 for instance, are held in substantially one planeby means of cross bars 64 and 65, corresponding to the cross 7 bars 36and 38 of Fig.2. In the modification i Fig. 6, glass panels 67,68 and69, correspond- 7 ing to the panels and 17 of Fig. 2, are held atsubstantially right angles by means of cross bars 70, 71 and 72 and. 73,corresponding to the cross bars 36 and 38 of Fig. 2 If desired myimproved metal window sashes-maybe mounted in pairs in window frames toslide vertically in guide channels in the, window frame.
